Be sure to wear protective goggles and gloves
when handling the lubricating oil and grease,
so that they do not get into your eyes or onto
your skin, otherwise inflammation can result.
Furthermore, do not drink the oil or eat the
grease under any circumstances, as they can
cause vomiting and diarrhoea.
Keep the oil out of the reach of children.
If the power switch and air need to be left on
when carrying out some adjustment, be ex-
tremely careful to observe all safety precau-
tions.
Use only the proper replacement parts as
specified by Brother.
If any safety devices have been removed, be
absolutely sure to re-install them to their origi-
nal positions and check that they operate cor-
rectly before using the machine.
Any problems in machine operation which re-
sult from unauthorized modifications to the
machine will not be covered by the warranty.
Have two people present to hold the machine
head with both their hands when tilting it back
or returning it to its original position.
